Geological Eras and Events

The video explores the history of life on Earth, spanning 4 billion years. It introduces the Geologic Time Scale, developed through the work of early geologists like Steno, Arduino, and Smith. The video covers the major eons and eras, including the Hadean, Archean, Proterozoic, and Phanerozoic, highlighting key events like the Cambrian explosion and mass extinctions. It discusses the rise of reptiles in the Mesozoic and mammals in the Cenozoic, emphasizing the impact of humans on the planet.
